IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 20,158, dated May V4,1858.

To all whom it may concern:

Beit known that I, JAMES J. JOHNSTON, of the city and county ofAllegheny, in the State ot' Pennsylvania, have invented certain new anduseful Improvements in Seed-Planters; and I do hereby declare that thefollowing is a full and exact descriptionthereof, reference being had tothe accompanying drawings, and to letters of reference marked thereon,similar letters referring to similar parts.

The nature ot my invention consists in an arrangement for lifting up andlowering down the share of the planter and cutting ofr the seed from theseed-chambers, and also in an arrangement ot' iiexible bottoms in theseedchambers.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, Figure 1 is a perspective view of theplanter. Fig. 2 is a side view of the planter, and represents the sharelowered down. Fig. 3 is an end view of the planter. Fig. 4is a side viewofthe planter, and represents the share raised up andthe seed-chambersclosed. Fig. 5 is a sectional view lengthwise ofthe planter. Fig. 6represents the share and a broken section of the cylinder in which theaxle or drum revolves which contains the seed-chambers. Fig. 7 is asectional view of the axle or drum which contains the seed-chambers.Fig. Sis atop view ot the axle or drum which contains the seedchambers.

In the accompanying drawings, a: is the axle or drum which contains theseed-chambers a. To the axle or drum .r is attached the front wheels,p.b is the flexible bottom. The bottom b of each seed-chamber is securedto a rod, d, which passes through a division-piece, e. The Iiexiblebottom is held up to its place by a coil-spring, c, which is placedaround therod d, and between the flexible bottom b and thedivision-piece e. The axle or drum .r is revolved in the cylinder f bymeans of wheels p. By this arrangement of the axle or drum cylinder f,bottoms b, rod d, springs o, and division-piece e, one chamber, inreceiving seed, causes the other chamber to deposit the seed in it intothe depositing-tube g. The cylinder f is attached to the frame q, and tothe cylinder f is attached the depositing-tube g.

To the depositing-tube g are attached two lugs, t. The share h is heldto the lugs t by a rod, u. The share 7L is so constructed that the fullforce thrown on it will be thrown from the share to the rod u anddepositing-tube g.

To the share h is attached a rod, i. This rod i is connected to a lever,j. To the lever j is attached also a sliding gate, k. The sliding gate7c is used for the purpose of cutting oif the seed from theseed-chambers a. By means of this arrangement the share It can be raisedso as to he made inoperative, and the seed is cut oft' from the chambersa, making them also inoperative. Thus the share h and seed-chant bers aare made operative or inoperative sim ply by raising or lowering theleverj, which can be done with ease by the operator when between thehandles lr of the planter.

o is the hopper.

s is the clevis. i

n is a roller used for the purpose ot' pressing the earth over the seed.

Z is a strip which is secured to the back end of the hopper o, and isused for the purposeof holding up the lever j.

m are the pedestals of frame q. In these pedestals are placed thejournal-boxes for the. axle or drum .fr and roller n.

Having thus described the nature, construction, and operation ot' myimprovements in seed-planters, what I claim as of my invention, anddesire to secure by Letters Patent ofthe United States, is

l. The arrangement of' the exible bottoms b, springs c, rod d, anddivision-piece e in the seed-chambers a, as herein described, and forthe purpose set forth.

2. The arrangement of the depositingtube g, with lugs t, share h, rodfi, lever j, and sliding gate k, as herein described, and for the purpose set forth.

JAMES J. JOHNSTON.
